Abstract: A device may include a transceiver configured to access a communication network including a primary cell and a secondary cell, and a device controller configured to receive, on the secondary cell, scheduling information for the primary cell, and monitor a common search space for the primary cell. The device controller may he configured to selectively monitor the common search space for broadcast information. The device controller may be configured to selectively monitor the common search space based on a type of the common search space on the primary cell. A method may include scheduling, by a first scheduling mechanism, a primary cell, wherein the first scheduling mechanism comprises scheduling the primary cell by a secondary cell, scheduling, by a second scheduling mechanism, the primary cell, and deactivating the secondary cell based on switching from the first scheduling mechanism to the second scheduling mechanism. The second scheduling mechanism may include self-scheduling.

Abstract: A system and a method are disclosed for providing enhancements to Semi-Persistent Scheduling (SPS) to match traffic, while also providing power savings, resource utilization and HARQ enhancements related to traffic and SPS configurations. A SPS configuration may include one or more occasions in a Physical Downlink Shared Channel (PDSCH) of a wireless network for traffic for a wireless device. In response to the SPS configuration, the wireless device receives the traffic in the scheduled occasions. The SPS configuration may include one or more occasions in at least one time slot in a SPS period. At least one occasion may align with a target periodicity of the traffic. The SPS configuration may include different configuration states, and a Downlink Control Information (DCI) message may be used to indicate to a wireless device which SPS configuration state to use to receive the traffic.

Abstract: A system and method for multiplexing uplink communications. In some embodiments, the method includes: multiplexing, by a User Equipment (UE) a Low Priority (LP) Hybrid Automatic Repeat Request acknowledgment (HARQ-ACK) codebook and a High Priority (HP) HARQ-ACK codebook in a first Physical Uplink Shared Channel (PUSCH), the multiplexing including mapping the HP HARQ-ACK codebook after a first symbol that follows a Demodulation Reference Signal (DMRS) and that does not include any DMRS Resource Elements (REs).

Abstract: A system and method for managing downlink data transmissions with HARQ feedback disabled. In some embodiments, the method includes: receiving, by a User Equipment (UE), a downlink data transmission with Hybrid Automatic Repeat reQuest (HARQ) feedback disabled; and multiplexing, by the UE, a plurality of HARQ-acknowledgment (HARQ-ACK) information bits to form a HARQ-ACK codebook, wherein the multiplexing of the HARQ-ACK information bits does not include multiplexing a HARQ-ACK information bit for the downlink data transmission in the HARQ-ACK codebook.

Abstract: A device, such as a UE, and a Transmit and Receive Point (TRP) in a High-Speed Train-Single Frequency Network (HST-SFN) are disclosed that provide network-assisted frequency-offset compensation for the device. The device includes a receiver that receives a first reference signal and a second reference signal sent over a wireless network from a first TRP. The first reference signal corresponds to a QCL RS of the second reference signal. The device receiver determines delay-spread and average-delay information for a path between the first TRP to the device based on the first reference signal. The device receiver further receives a third reference signal from a second TRP that includes Doppler-shift and Doppler-spread information, and corresponds to a QCL RS of a fourth reference signal transmitted from the second TRP or corresponds to the second reference signal transmitted in a SFN manner from the first TRP.

Abstract: A method may include multiplexing control information on a physical channel in a communication system, wherein the control information comprises a repeat request acknowledgment portion, and allocating an amount of resources of the physical channel for the repeat request acknowledgment portion based on an amount of a type of acknowledgment included in the acknowledgment portion. The type of acknowledgment may include an acknowledgment for dynamically granted traffic. The amount of resources may include a reserved amount of resources based on the amount of acknowledgment for dynamically granted traffic being less than a threshold. A method may include multiplexing control information on a physical channel in a communication system, wherein the control information may include a repeat request acknowledgment portion, and allocating an amount of resources of the physical channel for the repeat request acknowledgment portion based on a threshold, wherein the threshold is variable.

Abstract: Methods and apparatuses are provided in which a UE reports capability information indicating a first set of pairs and a second set of tuples. Each pair indicates serving cells configured for per-slot and per-span monitoring. Each tuple indicates serving cells configured for per-slot and per-span monitoring in an MCG and an SCG. A first pair of values for the MCG and a second pair of values for the SCG are received. A first value in each pair is a maximum number of serving cells configured for per-slot monitoring, and a second value in each pair is a maximum number of serving cells configured for per-span monitoring. A monitored candidate limit per slot is determined for the MCG and the SCG based on the first value. A monitored candidate limit per span is determined for the MCG and the SCG based on the second value.

Abstract: Methods and apparatuses are provided for monitoring a physical downlink control channel (PDCCH). A user equipment (UE) reports capability information indicating one or more tuples. Each tuple indicates a combination of serving cells configured for per-slot and per-span monitoring that the UE is capable of supporting. An indication is received in response to the capability information. A pair of values is determined based on the indication. A first value is a maximum number of serving cells configured for per-slot monitoring, and a second value is a maximum number of serving cells configured for per-span monitoring. A monitored candidate limit per slot is determined based on the first value. A monitored candidate limit per span is determined based on the second value.
